       2.1.3  Installation_Method  All of the subsystems for
       FDDIVisualyzer can be installed using IRIX.  You do not need
       to use the miniroot.

       2.1.4  Prerequisites

       FDDIXPress.sw.FDDIXPress                FDDIXPress software
                                               3.4

       eoe1.sw.unix                            Operating system
                                               IRIX 5.2 (or later)

       2.2  Installing_the_Software

       Use the IRIX installation method to install the FDDIXPress
       software.  Step-by-step instructions are provided below.

       Note:  More detailed explanations about the IRIX
              installation method are located in the IRIS Software
              Installation Guide. You may find the following
              sections especially useful: 4.2 and 4.7.6.

              If you are not sure how to use inst, Chapter 5 in the
              IRIS Software Installation Guide provides details.

         1.  In a shell window, become superuser:
             % su
             Password: thepassword
             #

         2.  Invoke the inst utility with the command below:
             # inst
              {the inst menu appears}
             Inst>

         3.  When the inst prompt appears (Inst>), use the from
             command to indicate the location of the FDDIVisualyzer
             software.  Table 10-3 in the IRIS Software
             Installation Guide summarizes the entries for this
             command.

             The command below can be used when the location is a
             local CD-ROM:
             Inst> from /CDROM/dist

         4.  When you are ready to install FDDIVisualyzer, use the
             command below to prepare for installation:
             Inst> install fddivis

         5.  Then use the command below to install the software:
             Inst> go

         6.  When the installation completes successfully, quit:
             Inst> quit

       3.  Additional_Information

       3.1  Notes_on_Operational_Parameters

       The following items describe some of FDDIVisualyzer's more
       interesting operational parameters:

          o This release of FDDIVisualyzer supports the SMT 7.2
            ``unknown address'' type (00-f8-00-00-00-00).

          o Service registration for this release is renewed every
            10 minutes.

       3.2  Additions_and_Changes

       This section describes additions and changes in this
       release.

          o A problem with registration (generation of NIF frames)
            immediately following clock resets has been fixed.

          o Timestamp displays for the SMT statisitcs have been
            changed so that values over one day old can be
            interpreted correctly.

          o FDDIVisualyzer has been made more robust in its
            response to changes in the system's time (clock).

       3.3  Known_Problems_and_Workarounds

       This section describes limitations and known problems with
       FDDIVisualyzer release 3.4.

          o To quit the Help window in the Display, Capture,
            Tutorial, or Status Mode, you must be in that mode.

          o If the NIF information collected has too many unknown
            or incorrect values, FDDIVisualyzer becomes confused
            and draws an incorrect ring map.

          o If there are cascaded concentrators in a ring,
            FDDIVisualyzer has difficulty determining to which
            concentrator a slave station is attached.

          o If ``token display'' is on, window pop-up menu
            selection is difficult because the pop-up menu is
            overwritten by the overlay plane redraw.

          o FDDIVisualyzer gets confused by ``tree mode'' dual MAC
            concentrators.  In the presence of dual MAC
            concentrators, FDDIVisualyzer may report the











                                  - 2 -



            connectivity of the last child of the concentrator as
            unhealthy even if the last child's connectivity is
            healthy.
